These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Zoe waiting by Jaxy's bed when she's in the hospital after an accidental overdose. It's especially touching because until then, Jaxy thought that Zoe was cheating on her with a man. Zoe then sets her straight.
All of Nervous and Pascal's interactions.
The end of Chapter 25: Johnny, Ripp, and Ophelia all sharing a bed.
Let's just try and come up with a few examples, shall we? Well, we have Ripp hearing that full aliens are intersex and so becoming abnormally curious about whether Johnny is the same, Ripp listening to Johnny and Ophelia have sex through the walls, Johnny washing Ripp in the bath after he has a fight with Tank, Johnny fighting Ripp to the ground and then straddling him and leaning in quite close after finding out that Ripp and Ophelia have kissed, Johnny requesting that Ophelia kiss him the way she kissed Ripp, Ripp tearfully telling Johnny that he loves him after making out with Frances while drunk, Johnny watching Ripp having sex with Ophelia and noting that seeing him in action was 'sublime', Ripp's apparent desire to have a threesome with Johnny and Ophelia and joy at being able to sleep in the same bed with both... And these are just some of the more obvious examples.
Ultimately, Ripp's interest in Johnny becomes canon, but whether or not Johnny felt the same way is yet to be resolved.
Tear Jerker: Many scenes in Chapter 36, especially Johnny deciding to leave with the aliens without being able to say goodbye to Ripp, and his goodbye to Ophelia.
